Your central heating and cooling system consists of two main parts: an outdoor unit (like a heat pump or air conditioner) and an indoor unit (like an air handler or furnace). When matched with a heat pump, an air handler circulates both cool and hot air throughout the seasons. Plus, air handlers make a significant contribution to the overall efficiency of your entire heating and cooling system. The more efficient your air handler is, the less work your outdoor unit has to do to keep your home comfortable.

It’s possible. Check out our air handler troubleshooting tips to see if the problem has a simple fix.

Use our Repair or Replace tool to help decide whether repair or replacement is the better option for you. Then contact your local Trane dealer to schedule service.

Your air handler installation cost will vary based on the unit you choose, whether you’re installing a heat pump at the same time, the capacity of the unit, the number of cooling stages, and more. We list some price ranges above for some of our air handling units, but the best way to find out the cost is to contact your local Trane dealer.

You can expect a new Trane air handler to last 15 years or more with regular maintenance. A heat pump/air handler split system works hard year-round to heat and cool your home. Change your filters regularly and schedule professional HVAC maintenance at least once a year, or each spring and fall before the cooling and heating seasons begin.

As part of ongoing improvement, the HVAC industry is in the process of transitioning to using a new refrigerant in newly manufactured units, including air conditioners and heat pumps. It’s called R-454B and is more sustainable than the most recent refrigerant, R-410A.

For new units listed on our website, you will see an icon indicating which units are using the new R-454B refrigerant. The icon will also appear next to a compatible air handler. Your air handler will need to “match up” with your heat pump. You can also find the type of refrigerant listed in the model specifications.

You can also contact your local Trane local dealer to learn more about refrigerants and product availability.
